Re: Master Cylinder PSI

There is a hose at the rear also. The hoses get old and plug up the inside and restrict flow. A common problem on older cars.

My calculations are nearly the same.
Many reference materials say that on drum brakes you need +500 PSI at the wheel cylinders. I'm not a good enough
mathematician to calculate the result of hydraulic fluid leaving the 1" master cylinder at +/- 125 PSI & passing thru a 3/16"
line. I guess I'll call me Princeton educated physics professor buddy & give him the problem.
Thanx for your help
